A Better Understanding of Odour
Posted in: Environment by admin on January 1, 1999 | No Comments
Odours generated from intensive livestock operations are growing in public concern and in many cases can limit location of newly built facilities. Recent work by Kenneth Adams of Reid Crowther studied the distribution of odour plumes generated from hog buildings. Odour plumes were determined to be very narrow, and dependant on wind and weather conditions. Information gathered from this study will assist engineers in using prevailing wind patterns to assess most suitable location for new swine buildings.
FarmFacts: Holding Pond Site Selection and Design
Posted in: Environment by admin on | No Comments
Livestock operators may need to contain contaminated runoff from feedlot facilities, silage pits or manure piles to prevent surface water pollution. Control works consisting of diversion ditches/dikes and holding ponds may be needed to contain the runoff. Include holding ponds as part of the feedlot design, which incorporates proper pen slopes to provide good drainage and pen drying. Construct holding ponds in impervious soils, or use man-made materials or imported clay as a liner to provide ground water protection.
The site selection process for the facility and the holding pond is a step by step process. The cost to the developer (time and financial) will increase with each step along the path. The geotechnical nature of the site and regulatory requirements will influence the required commitment from the developer. All sites require pre-screening and initial soils evaluation. For some sites this work will identify the need for a detailed site investigation.
The contruction technique used for holding ponds will determine the effectiveness of the soil seal formed. Detailed engineering may recommend installation of sampling wells to monitor seepage from holding ponds and to determine the effect on ground water quality. A regular monitoring program will allow corrective action to be taken when necessary

Strategies to alter nutrient excretion
Posted in: Prairie Swine Centre by admin on | No Comments
Nutrient management is becoming increasingly important for the swine industry worldwide. However, the situation on the Canadian Prairies cannot be compared tot eh situation in The Netherlands or North Carolina. That said, sustained attention in the media to nutrient management problems elsewhere supports a proactive approach to study strategies to alter nutrient excretion patterns, and perhaps gain economically in the process. Projects are underway to study nutritional strategies to alter excretion patterns of nitrogen and phosphorus, the two most problematic nutrients in manure.

Domestic animals' fear of humans and its effect on their welfare
Posted in: Welfare by admin on | No Comments
This review paper examines the issue of animal’s fear of humans and how it affects welfare. Sections include: the relationship between fear of humans and productivity; effect of aversive handling on fear and productivity; effect of gentle handling on fear and productivity; physiological effects of handling; effect of the stockperson on fear and productivity; effect of stockpersons’ attitudes; animals’ ability to discriminate stockpersons; and, solutions to fear of human problems. Differences among species are identified and discussed, including the sensory systems used and their ability to distinguish between people.
